[ warning: LOW reference: vaddr=0x00000000000000bc, exception TLBS, pc=0xffffffff8003f3e8 <badaddr+0x14> ]


>How-To-Repeat:
- download kernel newer then dec.2009
ftp://ftp.jp.netbsd.org/pub/NetBSD-daily/HEAD/200912310000Z/hpcmips/
- boot NetBSD/hpcmips machine.
- if you don't have hpcmips machine, install pkgsrc/emulators/gxemul 
and run
# gxemul -e mobilepro770 -X -M 512 kernel/netbsd20091201

>Fix:
On vr_find_dram,comment out badaddr check.
cvs rdiff -u -r1.55 -r1.56 src/sys/arch/hpcmips/vr/vr.c
